Stop staring at a stopwatch mid-burpee. This is a HIIT interval timer that calls every work and rest phase out loud, so you stay in the burn and just keep moving until the round is done. Most timers make you glance at the screen between rounds. This one runs the whole session for you: a full-screen ring flips from work-red to rest-teal while voice, beep and haptic cues fire on every phase change and final countdown. Train Tabata, EMOM, sprint ladders or a circuit you build yourself — tap start, follow the cues, empty the tank.
